1. A device for occluding an aperture in tissue or a vessel, the device comprising:

  • a hub aligned with a central axis of the device and configured to removably attach to a deployment tool for deploying the device at the aperture;

    a first flexible wire attached to the hub and a second flexible wire attached to the hub, wherein each of the first and second wires is comprised of a shape memory material, wherein each of the first and second wires is shaped into a first geometric form, a second geometric form, and a third geometric form, such that, in a deployed configuration, the first geometric form of the first wire and the first geometric form of the second wire form a first plate in a first plane, the second geometric form of the first wire and the second geometric form of the second wire form a second plate in a second plane that is parallel to and remote from the first plane, and the third geometric form of the first wire and the third geometric form of the second wire form a third plate in a third plane that is parallel to and remote from both the first and second planes, and the first and second plates are separated by a first waist formed from two portions of the first wire and two portions of the second wire, and the second and third plates are separated by a second waist formed from an additional two portions of the first wire and an additional two portions of the second wire, and the two portions of the first wire and the two portions of the second wire each include a first curvature and a first length, the additional two portions of the first wire and the additional two portions of the second wire each include a second curvature and a second length, the first length differs from the second length, and the first curvature differs from the second curvature, andwherein the additional two portions of the first wire and the additional two portions of the second wire of the first waist and the second waist are substantially centered about a longitudinal axis of the device in the deployed configuration.
